How to clear font cache filled with emoji characters?

Question

I am developing keyboard extension for iPhone. There is an emoji screen smilar to Apples own emoji keyboard that shows some 800 emoji characters in UICollectionView

Answer 1

I am guessing that you are loading the images using [UIImage imageNamed:], or something that derives from it. That will cache the images in the system cache.

You need to load them using [UIImage imageWithContentsOfFile:] instead. That will bypass the cache.

(And if that's not the problem, then you'll need to include some code in your question so that we can see what's happening.)
